Abstract

A vertically elongated container for drill pipe depends from and opens upwardly through the drilling platform of an offshore drilling rig in closely spaced relation to the rotary table. A power controlled pivotally mounted chute is associated with the container and selectively moves between a first position inclined toward the rotary table for the introduction and removal of pipe to and from the container by the derrick apparatus, and a substantially vertical position within the container for cooperation with handling apparatus utilized to manipulate the pipe within the container.

Claims

1. A pipe rack system for well drilling apparatus including a platform with a rotary table in operative position thereon and a drilling derrick rising thereover, said pipe rack system comprising a vertically elongated pipe container rigid with and depending from said platform in closely spaced relation to the rotary table, said container opening upwardly through said platform, said container having a base and peripheral walls including a near wall between the container and the rotary table, a pipe rack within said container, pipe handling means operative for a manipulation of pipe within said container, a pipe chute positioned within said container adjacent said near wall for receiving and supporting pipe along the length thereof, said pipe chute being movable between a first substantially vertical position orientating chute-received pipe substantially vertically and in cooperative relationship with the pipe handling means, and a second position inclined toward the rotary table for selective reception of pipe into or discharge of pipe from the container, said chute having a lower end and an upper end, means pivotally mounting the lower end of the chute inward of said near wall, and power means engaged with the chute adjacent the upper end thereof for a pivotal movement of the chute about the lower end between said first substantially vertical position for orientation of pipe in cooperative relationship with the pipe handling means and said second position inclined toward the rotary table for selective reception or discharge of pipe.

2. The system of claim 1 wherein said near wall includes an opening therein extending downward from the upper end thereof in alignment with the upper portion of the chute, said chute, in the second position thereof, extending through said opening into close proximity to the rotary table.

3. The system of claim 2 wherein said opening is of a size so as to closely receive said chute.

4. The system of claim 3 wherein said platform, outward of said wall and in alignment with the wall opening, includes a removable section so as to selectively expose the upper end of the chute in the second position thereof and provide a complete working surface when the chute is in the first position thereof.

5. The system of claim 2 wherein said platform, outward of said wall and in alignment with the wall opening, includes a removable section so as to selectively expose the upper end of the chute in the second position thereof and provide a complete working surface when the chute is in the first position thereof.
